Review on JSP Manufacturing Plastic Pressure Treated by Jim Ledbetter

Bought these caps to extend the life of the 4x4 PT bars used for speed limit signs and reflectors along the roadway. A set of 16 pieces arrived on time. One of the four sides of each lid had a small indentation, probably a guide for a screw or nail; I then pre-drilled this tab (and the corresponding one on the opposite side) to make pilot holes for the small screws used to attach it to the rack. Caps sit well on poles of varying ages and dryness; All of the caps appear to have the right balance of stiffness and thickness to stay in place while still being flexible enough that none of them show any signs of cracking or brittleness even after being screwed onto the posts. Enough to order another kit for additional posts that need this protection. FYI, they are somewhat glossy black and have a slightly pointed "roof" as seen in the photo.
